NEW DELHI: Five accused, including Railway Minister P K Bansal's nephew and suspended Member (Staff) in the Railway Board, were today remanded in judicial custody till May 20 by a Delhi court in connection with the Rs 10 crore railway bribery case.

CBI moved an application seeking to send them in judicial custody, saying the investigation in the case is in progress and it is still at an initial stage.

The agency told the court that crucial witnesses are yet to be examined and some documents are to be collected from various departments.

It said since the allegations against the accused are serious in nature and they are influential persons, they should be remanded in judicial custody.

The court accepted CBI's plea and sent all the five accused to judicial custody.

On May 7, accused Vivek Kumar, Dharmendra Kumar, businessmen Samir Sandhir and Rahul Yadav were also remanded in judicial custody till May 20 after the agency said their further custodial interrogation was not required.

One of the accused Sushil Dagga is yet to be arrested. All the accused persons have been booked by CBI for their alleged roles in the bribery case, in which a deal of Rs 10 crore was allegedly finalised for getting Mahesh Kumar appointed to a more lucrative post in the Railway Board as Member.
